I will make this awesome LED chandelier:
STEP-3
But i want to install this type of white LED on it:
Current: 23mA
Voltage: 3.2v
Quantity of LED on the chandelier: 160
I will use 5 LED "arrays" (or warever you say in english) and the 5 LED need 16V.
So my "problem" is exactly that, how can i make a Transformer that transforms 240VAC 50Hz in 15.3VAC (to be safe)?
I've saw many opinions, and this is what i've understood until now:
The LED at 15.3VAC will flicker. To mitigate the flicker i need to use a 0.22uF 400V capacitor. Hopefully the flicker will not be noticeable, but i'm not sure on this one, if someone knows what can be done to reduce flicker it would be awesome;
I'm connecting the LED in a way, that only AC current can power them up, that means that i just can't use DC current;
Someone said, that there could be "spikes" in the current, and to prevent the LED burning, it should be installed a 1K 1W Metal Oxide resistor, i agree, but i don't think the resistor value fits my need for more power.
And if i turn on and off fast the LED chandelier, i can end up burning all the LED! D: (i think the capacitor mitigates this problem too? i'm not sure)
Resuming, i need to know how to build a 240VAC 50Hz transformer to output 15.3VAC 100Hz? (maybe 100Hz mitigates the flicker completly?).
I have a schematic here, but i want to make sure that the chandelier will work at least one year without burning.

Maybe i just need to reduce the resistor a little to have 23mA instead of 20mA?
